In many ways, Union, in Old Town Pasadena, is the perfect Tuesday-night restaurant. With its vintage-storefront location, brick-walled interior and large windows looking out over Union Street, it feels like a restaurant on Main Street in small-town America. Seating only 49 people max, it’s also modest, and that intimacy, paired with the simplicity of the room, creates an atmosphere of easygoing comfort. The food Bruce Kalman is cooking, an ode to Italy through a Californian lens, is pretty much exactly what a relaxed weeknight out calls for.
